Very good extension, but I just came across a weird thing. I was viewing a local XML-page and these lines were added to the XML:

This is one of the most useful addons for Firefox!

Still, without any attempt to decry Bernard's good work, I do need to say it's a pity that addons like these are necessary at all, because web page designers do not think of any thing else besides shiny white pages with black writings. This might look good when you're sitting inside a well illuminated office, but that's not where everyone else is reading their pages.

This does not work.

Overall nice for programmers who are used to dark theme, subject to the technical difficulty to force a dark theme on complicated sites.
For end users, some CSS knowledge does help when the default style overrides do not work perfectly.

May a little feature request? A toolbar button to toggle between different dark styles would be very great, since some sites work better with `filter: invert(100%)`-based styles, some work better with `background: black; color: white`-based styles. Currently I have to go to the option page frequently to switch between the two families.

My chat window on facebook looks little weird, becase it makes the window black on elliptical area, the rest is still white.

Could You add whitelist or something like that?

Very helpful extension, thanks! | Очень полезное расширение, спасибо!

muito top *-*

This extension makes up for all the web apps out there that refuse to give their users a dark mode. Works great with Freshdesk!

Does not work on moto g5 plus with android pie BUT it works fine on my ZTE tablet with Android nougat

It doesn't work for the majority of websites I try to use it on.
